    摘要: A two-piece tire assembly 10 with a removable tread belt 12 for installing about the circumference of a tire carcass 14 is provided. The two-piece tire assembly 10 includes a tread belt 12 has a belt structure 90 having two or more belt layers 100, 110, 120, 130 each layer having one or more belts, wherein the belts in each layer 100, 110, 120 and 130 when viewed in a cross section have a. The tread belt 12 includes one belt layer 110 having 0 degree cord angles relative to an equatorial plane (EP) of the tread belt 12 and two belt layers 100, 120 having cords or opposite cord angles greater than 20 degrees, preferably in the range of 20 to 45 degrees. An optional fourth top belt layer 130 has cords oriented transverse or 90 degrees to the equatorial plane EP. The tread belt 12 has a radially inner surface 70 having one or more protruding circumferential ribs 72 or grooves 74 that fit into complementary grooves 18 or ribs 19 on an outer crown surface of the tire carcass 14. The inner surface of the tread belt 12 follows a linear, preferably flat profile across the tread belt 12 wherein the distance DL as measured from the axis of rotation to the inner surface of the tread belt 12 is constant between the equatorial plane and belt edge 115 such that DE equals DO. The tread belt 12 has a maximum axial belt width W at a radially inner surface. The carcass 14 has a maximum section width SW and ply line 20 having a maximum width P wherein W≦0.95P, BW≦0.85P and P
